Our products meet applicable ASTM A312, A213, A249 and A269 specifications, depending on the product type.
SS 316 contains molybdenum, which improves its resistance to chlorides and many corrosive environments compared with SS 304. This makes it suitable for marine equipment, chemical processing, pharmaceutical plants and industrial piping systems. We hold ISO 9001:2015 and TÜV certifications and supply customers in 85+ countries. Orders include EN 10204 3.1 mill test certificates for material verification and traceability.
What Are Stainless Steel 316 Pipes and Tubes?
Stainless Steel 316 Pipes and Tubes are hollow products made from an austenitic stainless steel alloy containing chromium, nickel and molybdenum. The addition of molybdenum improves resistance to pitting and crevice corrosion, particularly in chloride-containing environments such as seawater and coastal conditions.
SS 316 pipes carry liquids, gases and chemicals through industrial systems, while tubes are commonly used in heat exchangers, instrumentation and equipment requiring precise dimensions. Compared with SS 304, grade 316 generally performs better in environments exposed to salts and many corrosive chemicals.
These products are widely used in marine engineering, chemical processing, pharmaceutical manufacturing, food processing and water treatment plants. Available in seamless and welded forms, Stainless Steel 316 Pipes and Tubes come in different diameters, wall thicknesses and lengths to meet specific operating and project requirements.
Stainless Steel 316 Pipes and Tubes
High-quality Stainless Steel 316 Pipes and Tubes manufactured for demanding applications across chemical, petrochemical, pharmaceutical, marine, power generation and engineering industries. Available in seamless, ERW and EFW forms with various sizes, wall thicknesses and manufacturing specifications.
Why Choose Stainless Steel 316 Pipes and Tubes?
Stainless Steel 316 Pipes and Tubes are a practical choice for industries where exposure to salt, moisture and chemicals can cause corrosion. The addition of molybdenum gives SS 316 better resistance to pitting and crevice corrosion than SS 304 in many chloride-containing environments. This helps the material perform reliably in marine, chemical processing and water treatment applications.
Key reasons to choose SS 316 include:
- Better Corrosion Resistance: Handles many corrosive environments, including those containing chlorides.
- High Durability: Offers dependable performance in demanding industrial conditions.
- Good Heat Resistance: Maintains useful properties across a range of operating temperatures.
- Easy Fabrication: Supports common forming, machining and welding processes.
- Low Maintenance: Helps reduce corrosion-related repairs when properly selected and maintained.
- Wide Industrial Use: Suitable for chemical plants, pharmaceutical equipment, marine systems and food processing.
Choosing the right SS 316 product depends on the operating environment, temperature, pressure and required dimensions.

Material and Grades of Stainless Steel 316 Pipes and Tubes
The base grade is 316, and it comes in a few useful variants. We supply each one in pipe and tube form.
316: The standard molybdenum grade, with carbon up to 0.08%. It suits most chemical, marine and food applications.
316L: Low carbon, up to 0.03%. It is the preferred pick for heavily welded systems because it avoids weld decay.
316H: Higher carbon, between 0.04% and 0.10%, for better strength in hot service.
316Ti: Stabilised with titanium for long exposure to heat in the 450–850°C range.
316LN: Low carbon with added nitrogen, used when higher strength is needed alongside weldability.
Dual-certified 316/316L is also available and meets both chemistry limits in one pipe. All grades are supplied in the solution annealed condition.
Stainless Steel 316 vs 316L Pipes and Tubes: What Is the Difference?
316 and 316L share the same chromium, nickel and molybdenum. The difference lies in carbon, and that one number changes how each behaves after welding and under load.
| Point | 316 | 316L |
|---|---|---|
| Carbon | 0.08% max | 0.03% max |
| Minimum yield strength | 205 MPa | 170 MPa |
| Minimum tensile strength | 515 MPa | 485 MPa |
| Behaviour after welding | Can sensitise in thick sections | Resists weld decay |
| Best for | Higher strength, hot service | Heavy welding, corrosive fluids |
If your pipe will be welded on site and never heat treated, 316L is the safer choice. If strength at temperature matters more, go with 316 or 316H. For simple water, food or air lines with no chlorides, 304 can be enough and costs less.

Stainless Steel 316 Pipes and Tubes Size and Weight Chart
Theoretical weight is calculated as (OD − Wall) × Wall × 0.02507, giving kg per metre with dimensions in mm. Real weight can vary slightly within standard tolerances.
OD and wall are in mm. Multiply the result by the pipe or tube length to obtain the total weight.

Stainless Steel 316 Pipes and Tubes Sizes, Dimensions and Schedules
A pipe is named by its nominal size (NPS or DN), but its wall thickness depends on the schedule you pick. Higher schedule numbers mean thicker walls, more pressure capacity and more weight. The table shows how the wall changes with schedule at two common sizes.
| Schedule | Wall at 2" (mm) | Wall at 6" (mm) | Typical use |
|---|---|---|---|
| 5S | 1.65 | 2.77 | Low-pressure, weight-sensitive lines |
| 10S | 2.77 | 3.40 | General process and water service |
| 40S | 3.91 | 7.11 | Standard industrial piping |
| 80S | 5.54 | 10.97 | Higher pressure and heavy duty |
| 160 | 8.74 | 18.26 | Very high pressure |
Tubes are ordered by exact OD and wall in mm, inches or BWG. If your drawing needs a non-standard OD, a special wall or an odd cut length, we make it to your drawing.

FAQs
Common questions about SS 316 pipes and tubes, grade selection, standards, finishes and testing.
Why is 316 better than 304 near the sea?
316 contains molybdenum, which helps the surface resist pitting from chloride in salt air and spray. 304 lacks it and can show rust spots sooner.
When should I pick 316L instead of 316?
Pick 316L for heavily welded systems that will not be heat treated afterward. The lower carbon prevents weld decay.
Which standard should I specify for 316 pipes?
Use ASTM A312 for pipe. Use A213 or A249 for exchanger tubes, and A269 for general tubing.
How do I calculate the weight of 316 pipe?
Use (OD − Wall) × Wall × 0.02507, with both values in mm, to get kg per metre. Multiply by length for total weight.
How is 316 different from 316Ti?
316Ti has titanium added to protect against carbide formation during long heat exposure. It is chosen for hot service, while 316 suits ordinary corrosion duty.
Can you supply polished 316 tubes for hygienic use?
Yes. We offer bright annealed, No. 4 and mirror finishes for sanitary and pharma applications.
Do you make custom sizes and lengths?
Yes. Special OD and wall combinations, cut lengths and bends are made to your drawing.
Which certificates come with the order?
We supply EN 10204 3.1 mill test certificates. Third-party inspection reports are available when the purchase order asks for them.
Which tests can I request before shipment?
Chemical analysis, mechanical tests and hydrotest or eddy current are standard. PMI, IGC, ultrasonic and radiography can be added on request.
Can 316 handle hot service?
It is used up to around 800°C depending on pressure and medium. For long exposure to heat, 316H or 316Ti is usually a better choice.
